# Introduction

The project aims to build a system to authenticate genuine products and track their origins using NFC chips and blockchain technology. Each product will contain an NFC tag with a unique ID stored. Mobile apps can scan these tags and verify against a blockchain record to determine authenticity.

**Key Technologies:**

* **NFC chips:** To store and retrieve unique product identifiers 
* **Mobile app:** To read NFC tags and connect to blockchain
* **Blockchain network:** To store product IDs and validation records transparently 
* **Smart contracts:** Business logic to authenticate NFC IDs via blockchain 
* **Cloud hosting:** To host backend API and off-chain components 

**Key Features:**

* Scan NFC tags on products using a mobile app to extract unique ID 
* Check ID against blockchain record to authenticate products 
* Transparently track validation history of each product on blockchain 
* Trace product origins back using supply chain data on blockchain
*  Tamper-proof system to build customer trust.
